The SX51 is an optical subassembly (OSA) with bi-directional capabilities. The OSAs are available as either the transmitter or receiver subassembly supporting up to four video- or data-lanes (3.5 Gbps each) along with a simultaneous bi-directional 5 Mbps data and communication channel, all on a single multimode fiber. The OSAs feature integrated driver/receiver electronics so the need for handling complex optoelectronics in the system design is eliminated and faster design-in times can be achieved. The OSA includes a ZIF-terminated flex circuit to allow for fast assembly and test in manufacturing without the need for any optical alignment. The SX51 makes it simple to add the benefits of optical links to any data, DVI or HDMI 1.4 application.
